Nutrient Management

nmp1.jpg The relationship between agricultural productivity and environmental protection are essential areas of the research and extension programs in the Department of Soil Science. Departmental efforts in this area result in improved nutrient recommendations for crop production and protection of NC water resources. Currently, our nutrient management program involves:

  • Development of efficient, site-specific, and environmentally sound fertilization programs for Christmas trees and apples in the mountain region (Ron Gehl), wine grapes (John Havlin), field crops (Carl Crozier and Deanna Osmond) and horticultural crops (Greg Hoyt).
  • Understanding of the chemistry and management of organic cropping systems (Carl Crozier, Greg Hoyt, and Alan Meijer).
  • Development and maintenance of nutrient decision support systems that both function at the watershed-scale and are applicable to field-scale soil fertility issues (David Crouse and Deanna Osmond).
  • Site-specific soil fertility and productivity management, with an emphasis on remote sensing and related geospatial technologies (Carl Crozier, David Crouse, and, Jeff White). More detailed information about these programs can be found in the Geographic Information Sciences Program.
  • Tillage effects on nutrients, water storage, and physical properties (Josh Heitman, Greg Hoyt, and Alan Meijer).
  • Determination of nitrogen availability coefficients from organic sources (Carl Crozier, Dan Israel, and Jot Smyth).
  • Soil acidity management (Jot Smyth).
  • Training certified nutrient management planners (Deanna Osmond and Karl Shaffer)
